Download or read book Sperm Biology written by Scott S. Pitnick and published by Academic Press. This book was released on 2008-11-21 with total page 683 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sperm Biology represents the first analysis of the evolutionary significance of sperm phenotypes and derived sperm traits and the possible selection pressures responsible for sperm-egg coevolution. An understanding of sperm evolution is fast developing and promises to shed light on many topics from basic reproductive biology to the evolutionary process itself as well as the sperm proteome, the sperm genome and the quantitative genetics of sperm. The Editors have identified 15 topics of current interest and biological significance to cover all aspects of this bizarre, fascinating and important subject. It comprises the most comprehensive and up-to-date review of the evolution of sperm and pointers for future research, written by experts in both sperm biology and evolutionary biology. The combination of evolution and sperm is a potent mix, and this is the definitive account. The first review survey of this emerging field Written by experts from a broad array of disciplines from the physiological and biomedical to the ecological and evolutionary Sheds light on the intricacies of reproduction and the coevolution of sperm, egg and reproductive behavior
Download or read book The Fallopian Tube written by Jurgis G. Grudzinskas and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The examination of the human fallopian tubes was, until recently, restricted to observations on gross anatomical disposition and tubal patency. These studies, for decades, were the domain of doctors and physiologists whose primary interest was population control and family planning, funded largely by organisations and agencies seek ing alternatives to steroidal contraceptives. For a "worrying" but short period after the birth of Louise Brown in 1978 as the conse quence of successful in-vitro fertilisation and embryo transfer, the fallopian tube was considered to be "dispensable" given that the metabolic milieu in which human fertilisation takes place could be effortlessly reproduced in a Petri dish, in in-vitro fertilisation procedures. However, a number of factors have acted together to renew in terest in the fallopian tube, namely new techniques in cell biology, microinstrument developments (in particular in imaging), an inter disciplinary transfer of skills from interventional radiology and car diology to gynaecology, the surgeon's wish to improve surgical tech niques, and better techniques to monitor early pregnancy. These factors have led surgeons to develop the new diagnostic and ther apeutic strategies and techniques listed here. This volume contains contributions from the majority of keynote speakers at a conference held in London in April 1992 from which its title is derived. Better diagnostic procedures should lead to the implementation of rational effective treatments.

Download or read book Flagellar Mechanics and Sperm Guidance written by Jacky J. Cosson and published by Bentham Science Publishers. This book was released on 2015-11-04 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental research using spermatozoa, a highly specialized cell with organelles involved in gene transfer, energy supply and cellular motility, has always occupied the forefront of studies in cell and reproductive biology. Several spermatological experiments have focused on the attraction of a spermatozoon toward the egg – sperm chemotaxis or sperm guidance. This process ubiquitously occurs in the reproductive system of many organisms. After its discovery in the late 19th century in plants, sperm chemotaxis is known to play a crucial role in fertilization success in both plants and animals. Spermatology has expanded in focus in recent years, as the structure of molecules relevant to sperm chemotaxis has been recently determined in several species of invertebrates and vertebrates, which promises remarkable progress for understanding events relevant to sexual reproduction. Reflecting upon these trends in the long history of sperm chemotaxis, Flagellar Mechanics and Sperm Guidance gathers leaders in the field of spermatology, who have presented their experimental research on the chemical cues behind flagellate behavior in a variety of organisms including bikonts and spermatozoa of marine invertebrates and vertebrates (fish, amphibians and mammals). Reviews presented in this monograph provide both basic and detailed information on the initiation and activation of sperm motility at spawning, sperm thermotaxis, and other mechanics such as mathematical models of a spermatozoon swimming. A comparison between features of sperm chemotaxis among different organisms is also given. Flagellar Mechanics and Sperm Guidance will stir interest in spermatology research among a broad variety of readers including researchers, Ph.D. students studying reproductive biology and teachers involved in advanced biology courses.

Download or read book Male Sterility and Motility Disorders written by Samir Hamamah and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This conference, dedicated to the etiology and treatment of motility disor ders in spermatozoa and male sterility, attracted some of the finest investiga tors in the field. Standards were immensely high throughout, and discussions were meaningful and detailed. Analyses on disorders in sperm motility de mand a broad-based approach, involving cytologists, geneticists, andrologists, and embryologists, because the topic has many clinical and scientific over tones. Human spermatozoa are at the mercy of so many factors as they form and mature in the testis and epididymis. Their survival and fundamental char acteristics are essential for fertilization, and the male genome imposes its influence on the embryo as it becomes active in male pronuclei very soon after sperm entry into the oocyte. All of these fundamental aspects of sperm biology demanded a broad breadth of topics in the symposium. The opening session quickly got down to fundamentals with contributions from J.-L. Gatti, J.G. Alvarez, C. Gagnon, and H. Breitbart. They discussed the mechanism and regulation of motility, the metabolic strategy of human spermatozoa, the effects of exogenous fac tors such as antibodies, infections, and toxins, and finally the role of intracel lular calcium on sperm motility. To these topics, the postcoffee session on the first morning described the genetics of motility disorders and the etiology and management of necrozoospermia. The excellent presentation provided the background detail of the symposium and opened the way for the discus sion of various clinical aspects of the topic.
